3. Include tool and Java versions.
4. Tell us whether you are following GATK Best Practices.
5. Include relevant details, e.g. platform, DNA- or RNA-Seq, WES (+capture kit) or WGS (PCR-free or PCR+), paired- or single-end, read length, expected average coverage, somatic data, etc.
6. For tool errors, include the error stacktrace as well as the exact command.
7. For format issues, include the result of running ValidateSamFile for BAMs or ValidateVariants for VCFs.
8. For weird results, include an illustrative example, e.g. attach IGV screenshots according to Article#5484.
9. For a seeming variant that is uncalled, include results of following Article#1235.

#### ☞ Formatting tip!

Wrap blocks of code, error messages and BAM/VCF snippets--especially content with hashes (#)--with lines with three backticks (  ) each to make a code block as demonstrated here.

Is it possible to adjust the compression level of the BAM-files (like i picard etc). To optimize speed/disk long term disk usage, this would be advantageous when producing temporary/final BAM files, e.g. using the indelrealigner and printreads tools, respectively.

I'm not aware of any functions within GATK to do that, sorry.

Correction: my colleague points out that you can actually do that with the --bam_compression engine argument.

Is this information still correct? I've been looking around for --bam_compression` in the engine arguments, but I can't find it.

Hmm, I'm not finding it in any of the engine argument collections either. I see it as a standalone in walkers like SplitSamFile, but my understanding was that it was available to any bam writer. Let me check with the team.
